What it is

TimescaleDB is a PostgreSQL extension that adds time-series database capabilities for high-performance real-time analytics on time-series and event data. It enables creation of hypertables (automatically time-partitioned tables) with optional columnstore compression, allowing analytical queries on massive time-series workloads while maintaining PostgreSQL compatibility. Modular C extension architecture: src/bgw/ handles background job scheduling and workers; src/bgw_policy/ implements retention and compression policies; src/chunk* files handle time-partitioning core logic (chunk.c, chunk_constraint.c, chunk_index.c, chunk_scan.c, chunk_tuple_routing.c); src/cache.c provides hypertable…

Start here

Open these first:

• src/hypertable.c — Core hypertable management logic; entry point for time-series table creation and metadata handling.
• src/chunk.c — Chunk lifecycle management (creation, routing, constraints); essential for horizontal partitioning strategy.
• src/chunk_tuple_routing.c — Row insertion routing to appropriate chunks; critical path for write performance and correctness.
• src/bgw/scheduler.c — Background worker task scheduling; implements retention policies and compression jobs.
• src/extension.c — PostgreSQL extension initialization and hook registration; all Postgres integration entry points.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Evidence incomplete: no package.json, Makefile, or install script detected in file list. The README shows a convenience script (curl -sL https://tsdb.co/start-local | sh) and Docker approach, but these are not repeatabl…

Daily commands:

Build commands cannot be reliably derived from provided data. The src/CMakeLists.txt exists but contents not shown. Recommend: (1) verify PostgreSQL dev headers installed, (2) review src/CMakeLists.txt and src/build-def…

Key cautions & unknowns

• PostgreSQL version compatibility is critical: src/compat/compat.h suggests version-specific code branches exist. The extension loads into PostgreSQL's shared memory and process model, so misconfiguration can crash the…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
